E3 Premium Automotive Spark Plug

E3 Spark Plugs maximize the burn of the fuel/air mixture, which converts the fuel to energy and puts it to work. The result of a more complete burn is improved power and fuel efficiency, and lower carbon emissions.

Faster flame front converts fuel into More Power

More complete burn of the fuel means less "unspent" gas for better fuel efficiency

Consuming the fuel more completely means less carbon deposits and lower emissions

Great plugsGreat looking spark plugs, appear to be one piece bodies unlike OEM three piece plugs. Preforming great so far with about 500 miles on them. Feels good to have the power back and about half the price of the OEM plugs.

Best spark plugs on the marketBought a set of spark plugs for my Dodge Ram, and what a difference, it put life back into my engine and have it even more horse power then when I first bought the truck. I don't know why any one would buy any other brand.Had a big difference in the gas mileage as well. Bought a set for my Mustang as well, and wow its like a new car! Recommend for everyone to switch to E3's!

A great sparkplug at a great priceThe spark plug is probably the best plug at its price on the market for this engine, most other plugs are five dollars per plug more expensive and they don't last as long. My truck runs perfect with 163,000 miles on it, no hesitation At all. It no longer bogs down going up hills.my last set of plugs lasted about 45 to 55,000 miles and the plugs cost more than what I paid for these plugs. The only problem I had was that ford did not make a engine that is friendly to do it yourself mechanics. It's next to impossible to replaced them in under one hour.

E-3 Spark PlugsI us them in a 2005 F150 with a 5.4 engine and they work great. Looks like you can get about 75,000 miles on them before you need to replace them. I think they are the best plug on the market for 5.4 ford engines.
Try them I think you will like them>>>Jim

Should have listenedThe service tech told me Volkswagens were picky about the plugs and that I should use the ones he specified. I used the E3 and now the cars sputters when it starts. Runs ok, once started, but I will end up changing them out.

Great plugs - great priceI installed these plugs on my 2005 CTS at 150,000 miles - Wow! Runs great!
Pre-gapped - no worries. Well built.
Compared to some other premium plugs these are sturdy, and reasonably priced.

Noticable change at start up, power, and accerationI replaced the reliable factory spark plugs in my 2007 Lincoln MK LT at around 60k miles with the E3 Premium spark plugs. I managed to remove all 8 plugs without breaking any off in the well...lucky me, I heard and read the dreaded stories. So, I choose this plug because of the construction of the plug. Although the new E3 plug size was 5/8 vice 9/16, I had no trouble installing or torqueing the plugs to recommended specifications. So far the seem to be working fine. I noticed a smoother Idle and boost in power since the install. Its has only been a week so I'm still evaluating mileage and fuel economy. So far So good. the reason for the 4 star rating in ease of installation/use is because of having to change my plug socket due to the size difference (though it does add strength to the plug...a plus), and I would like to take the time to test drive my truck for a while. I will post an update after a few thousand miles.

Improved performaceAfter installing in my 2004 Sebring, I noticed a 7% increase in gas mileage and a definite increase in power and acceleration. Just recently installed a set in my Daughters Audi and it has never run as smooth as it does now.

smart choice for powerI put these spark plugs in my '78 Jeep J10 pickup truck . The engine has only around 4k miles on a rebuild . A very noticeable difference in the idling and the acceleration over the Bosch Platinums' I took out .
If a smooth running engine is your desire , the few extra dollars are for these plugs are a must .

Good and BadInstalled these in a 2001 Jeep Cherokee Sport and noticed improved throttle response and power. 50000 miles later still running great. Installed a set in a 2006 Chevy Trail Blazer got maybe 15000 miles and they started fouling out and had to replace them with a set of autolites. I guess it depends on the vehicle if they work or not.

E3 plugs are the bestI have purchased these for several vehicles. I get improved power and milage. I don't recommend them for the vehicles that require platinum plugs. I installed them in my Daughters Nisson sentra without telling her and after she drove it she wanted to know if I had done something to her car because she now had lots of power.

Wrong sizethe plugs coming out of a 5.4l 3v Ford triton engine are 9/16 these are 5/8. there is little enough room for the correct size socket without having to go bigger.

Core Charge

A "Core Charge" is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have a Core Charge, or Core Price, that works the same way as a soda can deposit.

Here's how the Core Charge works:

The part you are purchasing contains a component that is recyclable

The Core Charge deposit is charged at the time of purchase

When the recyclable component from your old part is returned to us, the charge is refunded to you

To receive your Core Charge refund, you can do either of the following:

Bring the part to any Pep Boys store along with your receipt or invoice (recommended)

Mail the part back to Pep Boys through the online return process

Please see our Returns Policy for more information on returning a core item.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Pep Boys core charge presented to you online today with your item is representative of the most common core charge. If you have any questions, please contact our Customer Care Center at 1-800-PEP-BOYS (737-2697) or visit any Pep Boys store.

SERVICE DESCRIPTION

Safety Rating is a combination of two values: Load Index and Speed Rating for P-Metric and Euro Metric tire sizes; and Load Range and Speed Rating in the case of heavy duty LT (light truck) sizes.

Speed Rating is based on the speed that the tire is designed to be driven at for extended periods of time. All tires in the in the U.S. are designed to maintain legal U.S. speed limits. The speed rating of tires must match the maximum driving speed of the vehicle.

Load Index is used on P metric and Euro Metric sized tires and denotes a tire's load-carrying capacity at a specified inflation pressure. The load index is represented by a number, the higher the Load Index Value the greater the load the tire can safely carry. Vehicle manufacturers recommend a maximum load capacity based on a recommended minimum load index.

UTQG - Uniform Tire Quality Grade

UTQG (Uniform Tire Quality Grade) is made up of three values: treadwear, traction and temperature.

Treadwear is a relative numeric score, based on manufacturer tests, showing how well a tire can be expected to wear compared to other tires. A higher score means a tire could be expected to wear better.

Temperature grades the tire's ability to withstand heat build-up, with A being the highest grade and C the lowest.

A - Over 115 mph
B - Between 100 to 115 mph
C - Between 85 to 100 mph
